Create logger for the module scope instead of using global logger

[danbeibei]

Follow the recommended way of using the logger in the generated Python modules (https://docs.python.org/3/library/logging.html) by creating a logger in each module: logger = logging.getLogger(__name__). Otherwise, at runtime, it will interact with other modules' loggers.

Here's the important line in the failing CI logs: https://github.com/jameskermode/f90wrap/actions/runs/12667563380/job/35301175384?pr=246#step:4:1691

Looks like a change in where ComplexWarning exception is located numpy, fix should be similar to https://github.com/dmlc/dgl/pull/7768/files
